What are the differences between cvt and servo stabilizer?

A CVT (Constant Voltage Transformer) stabilizer regulates voltage by using magnetic principles to maintain a steady output voltage, regardless of input fluctuations. In contrast, a servo stabilizer employs a servo motor and a variable transformer to adjust the output voltage based on real-time input changes, allowing for precise voltage regulation. CVTs are typically more compact and simpler, while servo stabilizers are more effective for larger fluctuations and offer better performance in high-load applications. Both serve to protect electrical equipment from voltage variations but operate using different mechanisms.
